If the 49ers were open to trading Kyle Shanahan

Would you trade a future pick for him? I'm all in for bringing Rizzi back, but I suspect the team will attempt to make a big move to try and bring hope back to the city.

Shanahan has been great, especially with good to average QBs. I believe Rattler can potentially turn into a pro-bowl QB under him and we'd also have a nice 1-2 punch with AK & Kendre Miller.
Give me one valid reason SF would be interested in trading Shanahan, then I'll entertain your query.
